Petrol Engine Hydraulic Rail Tamping Machine

The YD-22II Hydraulic Rail Tamping Machine is a flagship product recognized for its high-performance ballast compaction capabilities, critical for stabilizing the track structure. This machine is powered by a potent 9.5 kW GX390 petrol engine that drives a hydraulic system, generating a strong 22 kN exciting force and a high vibration frequency. The hydraulic operation ensures that tamping tools are inserted precisely to a depth of $110 mm below the sleeper, achieving optimal ballast density for improved track stability. With an impressive production efficiency of > 270 pieces (sleepers) per hour per group, the YD-22II is a labor-saving solution designed for double-line or wide-area single-line maintenance. Its advanced design makes it a best-selling unit, extending the service life of railway infrastructure.
